OIL BURNER.

Application filed. January 22,' 1925.

This invention relates to improvements in oil` burners and has for its principal object to provide one that generates and superheats its own steam.

Another important obj ect of the invention is to provide an oil burner of the above mentioned character wherein the water trap is provided for automatically regulating the water level in the boilingchamber thus insuring the eiiicient operation of the steam generating and superheating means.

A still further object of the invention is to provide an oil burner of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numeralsl designate like parts throughout the same:

The iigure represents a vertical sectional view of the burner embodying my invention.

In the drawing wherein for the purpose of illustration is shown the preferred'embodiment of my invention, the numeral vl designates the supporting base, the same being provided with a central threaded vopening 2. A circular burner head 3 extends upwardly from the base 1 around the opening 2. Threaded at its lower end in the threaded opening 2 of the base 1 and extending through the burner head 3 is the body member designated generally by the numeral 4.

The body member 4 is provided with a vertically extending water inlet passage 5, a supply pipe 6 being threaded into the lower end of the body member and communicating with the passage 5. An atomizing or mixing chamber 7 is arranged centrally within the body member and communication between the mixing chamber and the burner head 3 is provided through the medium of the fuel passage 8. The body member 4f is also provided with an oil inlet passage 9 which communica-tes with the at- Seral No. 4,069.

omizing or mixing chamber 7. An oil supply pipe 10 is threaded into communication with the oil passage 9 in the lower portion of the body member. A water outlet passage 11 is provided in the lower portion of the body member 4: and a discharge pipe 12 is associated with the outlet passage 11. The purpose of the water passage will hereinafter be more fully described. Y

Threaded on the body member 4 at a point, adjacent the top of the burner head 3 is the water boiling chamber 13. in superposed relation above the boiling chamber 13 and communicating therewith are a plurality of steam chambers 14. Each of the steam chambers is provided with a central opening 15 and extending through the openings 15 is the superheated steam conduit 16,the same being formed as an integral part of the body member t at the upper portion thereof. The steam chambers 14 are preferably in the form of hollow circular disks. The upper portion of the body member 4 is disposed within the boiling chamber 13 land formed in the upper portion of the body member is a water trap designated generally by the numeral 17. An inlet V18 is associated with the water trap 17 and provides a means whereby the water level in the boiling chamber 1.3 will be Arranged regulated. A superheated steam passage 19 Y Barile .plates such as are shown at 2O are l arranged on the steam conduit 16 at a point adjacent the openings 15 provided in the steam chambers 14. The burner head 3 has its inner periphery spaced from the body member 4 to provide an annular burner outlet 21.

In operation, the burner head 3 is initially primed, and water is admitted to the boiling chamber 13 through the pipe 6 and the water passage 5. The flames from the4 burner will heat the boiling chamber 13 causing steam to` be generated. The steam will pass upwardly through the steam chambersA which provide a means for superheating the steam, the steam passing through the openings 15 and around the baiiles 20. The steam chambers 1a' are also exposed to heat radiation and thereby the steam upon passing upwardly through the steam chambers will be properly superheated. The Water condensation will return to the -boiler chamber 13 and the trap 17 will talre care of an overflow in the chamber 13 so that the level of the water will be regulated automatically.

Thek superheated steam will enter the top of the steam conduit 16 and pass downwardlythrough the passage 19 in the body member i where it comes in Contact with the oil being admitted to the oil inlet passage 9 through the supply pipe 10. rlie superheated means and the oil will become atomized or mixed in the chambers 7 and the mixture will be discharged into the burner head 3 through the passage S. The combustible ygas produced will be a gas which will burn with intense -iame at the burner outlet 21, The water which may overflow ywill pass from the trap 17 into communication with the water outlet passage 11 and will be discharged vthrough the pipe 12.

It will thus be seen from the foregoing description, that an oil burner has been provided which will generate andsuperheat its own steam, the device being at all times positive and efcien't in its operation. The simplicity in which my device is constructed furthermore enables the same to be readily and easily assembled or disassembled.

While I have shown the preferred embodiment of my invention, it is to be :understood that various changes in the size,shape and arrangement of parts may be resorted to without departing from the spirit o the inventionand 'the scope of the appended claims. l

Having thus described the invention, what I claim is n 1; An oil burner of the class described comprising a supporting base havingr a centrally threaded opening, a burner head on said base around said opening, a body member threaded at its lower end into said threaded opening and extending through the burner head, said body member provided 2. An oil burner of the class described comprising a body member provided with an oil inlet, vand a mixing chamber in communication therewitlna burner head associated with the 'body member and having communication with the 'mixing l chamber, a wat-er boiling chamber associated with the body member, said body member `having means provided', therein for admitting water to said chamber, communicating superheatifng steam chambers arranged above the boiling chamber and communicating therewith, a superheated steam delivery conduit extending through saidv steam chambers communicating with said mixing chamber, and baffles on Y, said conduit adjacent the inlet of each steam. chamber.

3. An oil burner of the class described comprising a body member provided with an oil inlet, and a mixing chamber in communication ltherewith, a burner head associated with the body member, and having communication with the mixing chamber, a 'water boiling chamber associated with the body member, said body vmember having means provided thereinfor admitting water tosaidchamber, superimposed super heating'steamchambers arranged-above the boilingchamber having communication with-the latter and further communicating with each other, avsuperheated vsteam delivery conduit extending upwardly through. the superimposed steam chamber communicating at `itslower end withthe mixingchamber, and baffles on said conduit'adjacent the inlet of each of the superimposed steam chambers. y

In testimony whereof I aiix my signature.

WILL G. SHEEMAN.
